Response

Status: 200, Ok
Name Type Description

destination

snapmirror_endpoint

Endpoint of a SnapMirror relationship.

exported_snapshot

string

Snapshot copy exported to clients on destination.

healthy

boolean

Is the relationship healthy?

lag_time

string

Time since the exported Snapshot copy was created.

policy

policy

Basic policy information of the relationship.

preserve

boolean

Set to true on resync to preserve Snapshot copies on the destination that are newer than the latest common Snapshot copy. This field is applicable only for relationships with FlexGroup or FlexVol endpoints and when the PATCH state is "snapmirrored".

quick_resync

boolean

Set to true to reduce resync time by not preserving storage efficiency. This field is applicable only for relationships with FlexVol endpoints and when the PATCH state is "snapmirrored".

recover_after_break

boolean

Set to true to recover from a failed SnapMirror break operation on a FlexGroup relationship. This restores all destination FlexGroup constituents to the latest Snapshot copy, and any writes to the read-write constituents are lost. This field is applicable only for SnapMirror relationships with FlexGroup endpoints and when the PATCH state is "broken_off".

restore

boolean

Set to true to create a relationship for restore. To trigger restore-transfer, use transfers POST on the restore relationship.

restore_to_snapshot

string

Specifies the Snapshot copy to restore to on the destination after a break operation. This field is applicable only for SnapMirror relationships with FlexVol endpoints and when the PATCH state is "broken_off".

source

snapmirror_endpoint

Endpoint of a SnapMirror relationship.

state

string

State of the relationship. To initialize the relationship, PATCH the state to "snapmirrored". To break the relationship, PATCH the state to "broken_off". To resync the broken relationship, PATCH the state to "snapmirrored" for relationships with async policy type or "in_sync" for relationships with sync policy type. To pause the relationship, suspending further transfers, PATCH the state to "paused". To resume transfers for a paused relationship, PATCH the state to "snapmirrored" or "in_sync". The entries "in_sync", "out_of_sync", and "synchronizing" are only applicable to relationships of the sync policy type. A PATCH call on the state change only triggers the transition to the specified state. You must poll on the "state", "healthy" and "unhealthy_reason" fields using GET to determine if the transition is successful.

transfer

transfer

Basic information on the current transfer.

unhealthy_reason

array[snapmirror_error]

Reason the relationship is not healthy. It is a concatenation of up to four levels of error messages.
